In addition to being a loving wife and doting mother, Kailyn Lowry-Marroquin can now add "New York Times Bestselling Author" to her very impressive resume. The "Teen Mom 2" cast member announced the exciting news on Twitter last night, gushing: "I cannot believe Pride Over Pity became a NY Times best seller. THANK YOU to all of you. It means so much!"

Husband Javi was understandably delighted for Kail, tweeting: "My wife is a NY Times Best Selling author! I can't tell you how proud I am of her. Thank you everyone who bought the book! #PrideOverPity."

"Pride Over Pity," a memoir that includes stories of Kail's experiences with bullying, living in a homeless shelter and sexual assault, was released on Apr. 22 and landed on this week's Combined Print & E-Book Nonfiction list at #10. On the specific E-Book Nonfiction list, it snagged the #7 spot. That's our girl!
